Easy to check the fillet after soldering is finished.
2) Small, light, rectangular 2-chip network
Area ratio is 65% smaller than that of MNR32, while weight ratio has been cut 75%.
3) High-density mounting
Can be mounted even more densely than two 0603 chips (MCR03), and mounting costs are lower.
4) Compatible with a wide range of mounting equipment.
Squared corners make it excellent for mounting using image recognition devices.
5) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification.
Design and specifications are subject to change without notice. Carefully check the specification sheet supplied with the
product before using or ordering it.

Rated voltage
The voltage rating is calculated by the following equation.
If the value obtained exceeds the limiting element voltage,
the voltage rating is equal to the maximum operating voltage.

Before
using components in circuits where they will be exposed to transients such as pulse loads (short-duration, high-level loads), be certain to evaluate the
component in the mounted state. In addition, the reliability and performance of this component cannot be guaranteed if it is used with a steady state voltage that
is greater than its rated voltage.
